The valve self-adjusts for pressure differential and therefore eliminates the need for manual adjustment according to pressure differential after installation as is required with manual balancing valves. It self-adjusts to prevent exceed- ing design flow setting even as system pressure differential fluctuates with operation as long as the valve is within its pressure differential control range. The smaller range of SH-valves are all designed for double union end connection. They are available in two different valve housing sizes. Each valve has 51 different flow settings.
